Double-basket fire escape device for high-rise buildings

Abstract

The invention discloses a double-basket fire escape device for high-rise buildings, which comprises an elevator mechanism component, a support component, a hook, a left basket and a right basket and is characterized in that the middle of a frame in the elevator mechanism is provided with a screw rod and a rotary drum; nuts are embedded in the flange centers at the two ends of the rotary drum; a layer of steel wire rope is coiled on the rotary drum; the left beam of the frame is welded with a fixed pulley seat; the fixed pulley seat is provided with a pulley and a steel wire rope locking mechanism which is composed of an adjusting screw rod, a pressing plate, a sliding block, a guiding wheel and a sleeve; the right beam of the frame is sleeved with a moveable pulley seat; the left basket and the right basket are respectively hung at the two ends of the steel wire rope; and friction blocks are installed corresponding to the flanges at the two ends of the rotary drum. Compared with other escape devices, the device provided by the invention has the following advantages and beneficial effects: the left basket and the right basket are respectively hung at the two ends of the steel wire rope and one ascends while the other descends, without idle stroke, thus improving the working efficiency and saving the precious escape time; and the escape device is convenient to operate, safe and reliable and especially suitable for escape in an organized way in the places where people gather, such as hotels, shopping malls, student dormitories, office buildings and the like.
